 ListView: How to get item position

I would like to enable the user to move around the listview items and then
retrieve the order the user placed them in. How do I get an items position
in the ListView?
How do I get a list of the item in a list view by position order?

 ListView: How to get item position


The following code, which uses a VScrollBar as a spin control to move an
item up or down in a ListView control.  (The scroll bar has min and max set
to 0 and 2, respectively, and is initialized to 1).  I hope this fragment
gives you some ideas.

Private Sub ctlVMove_Change()
    Dim nOldValue As Integer: nOldValue = ctlVMove.Value - 1
    Dim nPrevItem: nPrevItem = nCurrentItem
    ctlVMove.Value = 1 ' Causes extra invocation of ctlVMove_Change with

    If nOldValue = -1 Then ' Moving toward top of list
        If nCurrentItem > 1 Then
            nCurrentItem = nCurrentItem - 1
        End If
        ' Moving toward bottom of list (if nOldValue=2)
        If nOldValue = 1 And nCurrentItem < lvTableNames.ListItems.Count
            nCurrentItem = nCurrentItem + 1
        End If
    End If

    Dim sTemp As String
    Dim liPrev As ListItem: Set liPrev = lvTableNames.ListItems(nPrevItem)
    Dim liCurr As ListItem: Set liCurr =
    liPrev.Selected = False
    liCurr.Selected = True
    sTemp = liPrev.Text
    liPrev.Text = liCurr.Text
    liCurr.Text = sTemp


End Sub
